Kornberg and Bernard L . Horecker used the Beckman DU spectrophotometer for enzyme assays measuring NADH and NADPH . They determined their extinction coefficients, establishing a basis for quantitative measurements in reactions involving nucleotides.

It has been shown using enzyme assays that the substrate for RhlA is hydroxyacyl-ACP rather than hydroxyacyl-CoA suggesting that it catalyses the formation of HAAs directly from the type II fatty acid synthase pathway ( FASII ).

Enzyme assay techniques detect individuals with lower levels of hexosaminidase A . Development of a serum enzyme assay test made it feasible to conduct large scale screening for Tay Sachs in targeted at-risk populations such as Ashkenazi Jews.

After enzyme assays, the strain of cyanobacteria expressing the NADPH utilizing enzymes produced the greatest amount of 1-butanol ( 29.9 mg / L ), exceeding that of strains that did not consist of the NADPH utilizing enzymes by four times.

Tay-Sachs disease has become famous as a public health model because an enzyme assay test for TSD was discovered and developed in the late 1960s and early 1970s, providing one of the first " mass screening " tools in medical genetics.
37.
Similarly, in an enzyme assay to measure the amount of an enzyme in a set of extracts, a positive control would be an assay containing a known quantity of the purified enzyme ( while a negative control would contain no enzyme ).
38.
The fact that the test is an enzyme assay is not crucial to the lead ( as it doesn't help the general reader's understanding ), and can easily be redacted from the lead . talk ) 05 : 25, 30 May 2009 ( UTC)

He also proved that Tay Sachs disease patients could be diagnosed by enzyme assay of hexosaminidase A . Further development of enzyme assay testing demonstrated that levels of both hexosaminidases A and B could be measured in patients and carriers, allowing reliable detection of heterozygotes.
